We have a very large client base and utilize Azure B2B for our client portals. We are seeing this more and more, and I echo what Jeremy has said. It's a very bad user experience, and very difficult to explain to the average user. I've been very impressed with B2B, but this is a big gap.
We’ve made several improvements in this area to support users who don’t have O365 or who are using email addresses that differ from their O365 login information (such as supporting proxy addresses, direct federation support, and email one-time passcodes), but we know there’s more work to do in this space. Please let us know what other scenarios are causing you and your guests the most pain so we can use that information to triage and prioritize future investments.
This is in our backlog, but votes and comments about how you would expect this to work are very helpful to our planning/designing the feature so please keep them coming.
Also, for some scenarios in this space Access Reviews (https://docs.microsoft.com/en-us/azure/active-directory/governance/manage-guest-access-with-access-reviews) can be a good way of removing users who no longer need access, including those who don’t have accounts anymore. (Thanks Shawn for pointing that out for everyone!)
